I have 2 separate .txt files displaying 2 matrices each:

As I am new to coding in general, would a kind soul help me with a rough script of the following in python?

I would like to compare the elements of the 2nd column vector of Matrix A with the last 2 columns of Matrix B, with the latter being the max and min values of a constraint (max = 1.05; min = 0.95).

The objective is to write an 'if' loop to check if MatrixA[:,1] falls within the constraints of MatrixB[:,11] and MatrixB[:,12].

In the case of a constraint violation, the script should throw an error message and Matrix B would not be generated.

Else, if MatrixA[;,1] is within the constraints, the script would run and successfully generate Matrix B.

Note: The matrices are dynamically generated by a separate program into .txt files. My main problem is going about pulling the values out from the individual matrix and comparing the values between the 2 .txt files containing Matrix A and B respectively.

Can you please share the code that you have tried?

Thanks very much for your reply! The following is basically what I am trying to implement.
My problem is with writing the code for comparing 2 matrices stored in .txt files.

    ])


rows = len(matrixA[:, 0]) #15 rows


for R in range(rows):

    if matrixA[R, 1] > matrixB[R,11] or matrixA[R, 1] < matrixB[R,12]:
        break
    print("Contraints violated!")

Additionally, how should I write the code to overwrite the contents of matrixA.txt with "Constraints violated!" in the case of the 'if' loop being true.

In the above example, I used values for the 2nd row of Matrix A which are not within the limits of the maximum and minimum values given in rows 12 & 13 of Matrix B

In the case of a non-violation, Matrix A should show the respective matrix which adheres to the limits given.

Thanks very much in advance!
